To meet the increasing requirements toward biobutanol, pervaporation membrane with high separation performance needs to be developed. In this work, a hydrophobic MAF-6 (RHO-[Zn(eim)₂]) was synthesized and its adsorption properties for 1-butanol was systematically studied, which are supposed to benefit the separation performance of polydimethylsiloxane (PDMS) membrane. The hydrophobic MAF-6 particles were therefore doped into PDMS to fabricate mixed matrix membrane. The morphology, chemical structure, and other properties of particles and hybrid membrane were fully studied by SEM, PXRD, FT-IR, TGA, and BET. Results demonstrate that the hydrophobicity of PDMS membrane is improved with the water contact angle increasing from 112.7° to 118.1° after being doped with MAF-6, as well as enhanced adsorption ability toward 1-butanol. More importantly, when doping MAF-6 into PDMS layer, the enhancements of 23.30% and 41.93% are separately observed in the separation factor and total flux to separate 1.5 wt% 1-butanol solution, compared with the PDMS membrane. In addition, the heat energy consumption of pervaporation process is decreased from 4.27 to 3.71 kJ g⁻¹ via the doping of MAF-6. Overall, this work confirms that the hydrophobic particle such as MAF-6 is not only conductive to enhance the separation performance of PDMS membrane but also helpful to decrease the energy consumption.

为了满足对生物丁醇日益增长的需求，需要开发具有高分离性能的渗透蒸发膜。在这项工作中，疏水性 MAF-6 (RHO-[Zn(eim) ₂]) 被合成并系统地研究了它对 1-丁醇的吸附性能，这应该有利于聚二甲基硅氧烷 (PDMS) 膜的分离性能。因此，将疏水性 MAF-6 颗粒掺杂到 PDMS 中以制造混合基质膜。通过SEM、PXRD、FT-IR、TGA和BET对颗粒和混合膜的形貌、化学结构和其他性质进行了全面研究。结果表明，掺杂MAF-6后，PDMS膜的疏水性随着水接触角从112.7°增加到118.1°而提高，对1-丁醇的吸附能力增强。更重要的是，当将 MAF-6 掺杂到 PDMS 层中时，分别观察到分离因子和总通量分别提高了 23.30% 和 41.93%，以分离 1.5 wt% 1-丁醇溶液，与PDMS膜相比。此外，渗透蒸发过程的热能消耗从4.27kJ·g降低到3.71kJ·g^-1通过掺杂 MAF-6。总的来说，这项工作证实了疏水性颗粒如 MAF-6 不仅有助于提高 PDMS 膜的分离性能，而且有助于降低能耗。
